Abstract

LA INCORPORACION DE UN SURFACTANTE DE POLI(SILOXANO-GLICOL) CON UN PUNTO DE CRISTALIZACION QUE VA DE 25 A 50 GRADOS EN UNA COMPOSICION DE LIBERACION DE MOLDE BASADA EN AGUA, QUE CONSTA DE UNA EMULSION O DISPERSION ACUOSA DE AL MENOS UNA SUSTANCIA EFICAZ DE LIBERACION Y PREFERIBLEMENTE AL MENOS UN AGENTE EMULSIONANTE QUE DA UNA CALIDAD MEJORADA DE LA SUPERFICIE DEL PRODUCTO DE ESPUMA. TAMBIEN SE REVELA UN METODO PARA LA PREPARACION DE UN ARTICULO DE ESPUMA DE POLIURETANO EN UN MOLDE MEDIANTE LA APLICACION A UNA SUPERFICIE DE MOLDE DE UNA COMPOSICION DE LIBERACION BASADA EN AGUA QUE CONSTA DE UN SISTEMA EFICAZ DE LIBERACION QUE SE ENCUENTRA EN ESTADO SOLIDO (ENDURECIDO) EN LA TEMPERATURA DE FUNDICION DEL MOLDE Y EN ESTADO LIQUIDO EN LA TEMPERATURA DE DESMOLDEAMIENTO, FUNDIENDO UNA COMPOSICION DE LA ESPUMA DE POLIURETANO EN EL MOLDE, CURANDO LA COMPOSICION Y DESMOLDEANDO EL ARTICULO DE ESPUMA. EL USO DE DICHO SISTEMA EN LA COMPOSICION ACUOSA DE LIBERACION DE MOLDE PROPORCIONA UNA REDUCCION DELOS DEFECTOS DE LA SUPERFICIE DEL ARTICULO DE ESPUMA DE POLIURETANO.
